Title: Optical tapping filters employing long period gratings
Inventor: VENGSARKAR ASHISH MADHUKAR
IPC: G02B6/287
Filed: 1996-02-06
Granted: 1999-03-30
Abstract: An optical filter comprises a plurality of optical fibers having a coupling region where the axially extending cores are closely spaced within a common cladding. The coupling region includes a long period grating for selectively shifting light of selected wavelengths from guided modes into non-guided modes. These non-guided modes are picked up by an adjacent core and light of the selected wavelengths is thus shifted from one core to another. The result is an optical filter particularly useful as a demultiplexer or a tapping device. In one embodiment the grating is formed in one of the cores. In an alternative embodiment, it is formed in the common cladding.

Title: High-speed data transmission in mobile communication networks
Inventor: RASANEN JUHA
IPC: H04B7/26
Filed: 1995-12-08
Granted: 2007-01-30
Abstract: In a mobile communication system according to the invention two or more parallel traffic channels are allocated for high-speed data transmission over the radio path. Different channel numbers (ch0, ch1, ch2, ch3) are assigned to these parallel traffic channels for the duration of the connection. The data of a high-speed data signal is inserted at the distribution point of the transmission end (Tx) into frames each of which is provided with a channel number indicating the parallel traffic channel used for the transmission. The frames transmitted in a traffic channel always contain the same channel number during the whole call. The frames are divided into parallel traffic channel in the sequential order according to the channel numbering. At the reception end (Rx) the dta contained in the frames is reassembled into a high-speed data signal in the sequential order according to the channel numbers in the frames. Additionally, frame numbering may be used within each of the traffic channels so that at least two successive frames always have a different frame number (fr0, fr1). As a consequence, the allowed delay offset between the traffic channels will increase with the number of the frame numbers, and the order of the frames will be maintained under any circumstances.
